Thanks!
Two very long parallel wires are set 5 apart. The point of interest, P, lies 2 and 3 away from the first and second wires, respectively. Suppose that each wire carries current I = 2a in the same direction, [ ]. Determine the contribution to the magnetic field at P from the current in wire 1. Determine the contribution to the magnetic field at P from the current in wire 2. Determine the net magnetic field at P from the two currents. Suppose that each wire carries current I in the same direction, [ ]. The force of interaction between the two wires is [choose one:] attractive. repulsive. Suppose that wire 1 carries current I 1 = 2 a [ ], while wire 2 bears I2= 2 a [ ]. Determine the contribution to the magnetic field at P from the current in wire 1. Determine the contribution to the magnetic field at P from the current in wire 2. Determine the net magnetic field at P from the two currents. Suppose that I1 = I [ ], while I2= I [ ], [i,e., same magnitude but oppositely directed]. The force of interaction between the two wires is [choose one:] attractive. REPULSIVE.Explanation / Answer
a) 1) magneti field at p due to wire 1 = B1 =uo*i/2*pi*r = 2*10^7 T........
2) magneti field at p due to wire 2 =B2 = uo*i/2*pi*r=1.34*10^7 T............
3) B2 is out side and B1 is into the page......
Bnet = B1-B2 = 0.667 T.............
b) attractive......
c) 1) magneti field at p due to wire 1 = B1 =uo*i/2*pi*r = 2*10^7 T........
2) magneti field at p due to wire 2 =B2 = uo*i/2*pi*r=1.34*10^7 T............
3) B2 and B1 are in sme direction.....
Bnet = B1+B2 = 3.34 T.............
d) repulsive
